VALVE MECHAN ISM.

Specification of Letters Patent.

Patent-ed Mar. 21, 1916.

Application sied :ranary 5, 191s. serial No. 70,491.

To all whom it may concern Be it known that I, VCARLI-I. ZWERMANN, a citizen of the United States, residing in the c ity and county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Valve Mechanisms, which the following isl a specification.

This invention relates to improvements in valve mechanisms.

My improved valve mechanism is especially designed by me for use on flushing tanks and I have shown the same as I have embodied itin such a structure.` My improvements may, however, be readily adapted for use in other relations.

The main object of my invention is to provide an improved valve mechanism which is simple and economical in its` parts, easily assembledand not likely to become disarranged in use. j

Further objects, and objects Vrelating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described inthe following specification. The invention Vis clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, `forming a part of this specification, in which:

Figure I is a front view of a flushing tank structure embodying the features of my invention, a portion of the walls of the tank being broken away to better disclose the arrangement of the parts. Fig. II is a detail horizontal section on aV line corresponding Vto line 2`2 of Fig. I. Fig. III is a detail vertical section on a line corresponding to line 3-3 of Fig. II. Fig. IV is a detail vertical section on a line corresponding to line i-4- of Fig.A II.

In the drawing similar reference characters refer' to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Referring to the drawing, 1 represents a tank, the tank shown being formed of sheet metal. The details of the water discharge and inlet means are not illustrated or described as they form no part of my present invention.

2 represents the stem of the discharge valve. The valve actuating lever comprises a pair of members 3 and i respectively, having journals 5 and 6, respectively, at one end and arms 7 and 8 respectively, at their other ends. These members 3 and i are formed of flat vstrips or bars of metal bent into an angle, as clearly appears in Fig. II.

The members are arranged oppositely back to back and secured rigidly together, preferably by spot welding, indicated at 9. The lever bearings 10 and 11 are secured on the inner sides of the front and rear walls 12 and 13, respectively, of the tank. The journals are arranged in their bearings to permit longitudinal movement for engaging and disengaging the journals from the bearings, the rear wall having a hole 14k therein opposite its bearing permitting the lever to be shifted rearwardly to engage and disengage the front journal 6 with its bearing 11. The lever is actuated by the finger piece 15, the shank 16 of which is arranged through a slot or aperture 17 in the front wall and secured to the front arm 7 of the lever. The rear arm 8 of the lever is provided with a series of holes 18 with which the valve stem or rod 2 may be engaged.

The finger piece 15 and its shank 16 serve to limit the journal disengaging movement of the lever so that when the parts are assembled the lever cannot be disengaged from its bearings without the vremoval of the finger piece. The finger piece thus serves the function of retaining the parts in their assembled relation as well as serving as a finger piece. The finger piece is preferably provided with a base of such dimensions that it also serves as a cover or shield for the slot or aperture 17 (see Figs. I and IV). The slot or aperture 17 is also of such dimension that it properly limits the movement of the finger piece, the sides or ends serving as stops for the shank thereof.

With the parts thus formed and arranged as illustrated, they are very simple and economical to produce and assemble and are durable and cannot become accidentally disassembled. The lever members 3 and l are preferably formed of flat strips or bars of iron, as stated, and galvanized or otherwise treated to prevent corrosion. It has been quite general practice to form corresponding parts of the valve mechanism of brass castings, but by arranging the parts as I have shown and described, they may be satisfactorily and very economically formed of iron.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

l. In a valve operating device, the combination with a tank having an aperture in its front Wall, a valve actuating lever consisting of a pair of members having journals at one end and laterally projecting arms at their other ends, said members being disposed oppositely back to back and secured to each other, journal bearings secured on the inside of the tank, there being an opening in the rear wall of the tank opposite the rear bearing to permit longitudinal movement for engaging and disengaging the front journal with its bearing, a valve connected to one arm of said lever, and a finger piece for the other arm of the lever provided with a shank arranged through said aperture, said linger piece constituting a shield for said aperture and means for preventing the disengaging movement of said journals in their bearings.

2. In a valve operating device, the com- Y bination with a tank having an aperture in its front Wall, a valve actuating lever consisting of a pair of members having ournals at one end and laterally projecting arms at their other ends, said members being disposed oppositely back to back and secured to each other, journal bearings secured on the inside of the tank, said journals being arranged in their bearings to permit longitudinal movement for engaging and disengaging the Jfront journal with its bearing, a valve connected to one arm of said lever, and a finger piece for the other arm of the lever provided with a shank arranged through said aperture, said finger piece conlstituting a shield fuorisaid aperture and its Wall, a valve actuating lever comprising a rock shaft portion With journals at its ends and a pair of arms, journal bearings secured on the inside of the tank, said j ournals being arranged their bearings to per-4 mit longitudinal movement for engaging Y and disengaging the front journal with its bearing, a valve connected to one arm oi' said lever, and a finger piece for the other arm of the lever provided With a shank arranged through said aperture, saidv linger piece constituting means for preventing the disengaging movement of said journals in their bearings. Y

4. In a valve operating device, the combination with a tank having an aperture in its Wall, a rock shaft disposed Within the tank, with journals at its ends, bearings therefor disposed to permit longitudinal movement of the rock shaft to facilitate inserting the same, an arm on the rock shaft extending opposite the aperture in said Wall, and a finger piece With a VSha-nk projecting through the said aperture and connected to the rock shaft arm for actuating the same and retaining it in place, as specified.

In Witness whereof, I have Vhereunto set my hand and seal in the presence of two Witnesses. Y Y
